Attendees

• Melva Peters (Chair)

ListServ Discussions

• List Serve Postings
  • email from Grahame - fluid orders - sent to the Pharmacy list
  • Nurse visit, delivered medication
    • would a home care nurse left medication(s) for the patient to take later, would that be an Administration, Dispense, Statement?
    • several responded that Dispense is most appropriate. If the nurse later confirmed the administration, that would be an Administration (with the patient as the information source).
    • some don't see this as a dispense ... more like a deliver. There is a Workflow resource for SupplyDelivery.

Action:  John H will respond to email with the SupplyDelivery option.

Zulip

• MedicationStatement
  • related to "do not do" - as in patient not to be given a certain medication
  • may come out of Negation project from Patient Care
  • a number of items included in this Zulip chat
    • patient not to be given medication
      • not likely a medicationStatement - is this a negative order?
      • has not come up for Cerner - may infer something like this from an allergy
    • doctor recommends that GP prescribes drug ABC

Action:  Melva to reach out to Philip to post tracker item

TR#10456 Renaming MedicationOrder to MedicationRequest Discussion

• Email received July 4, 2016 from Lloyd
  • The FHIR Workflow task force has been working for almost the past year to come up with guidelines to improve the consistency of how workflow (the process of requesting something to happen and then reporting the results of that request) are handled across all FHIR resources. Its scope encompasses clinical, administrative and financial resources. We've had relatively broad participation in the bi-weekly calls and very broad participation in the face-to-face sessions at HL7 WGMs.
  • While the project is still testing the recommendations using a variety of use-cases, we are sufficiently confident in the stability of the recommendations, that we voted last week to request all impacted work groups to apply the relevant changes to their resources for inclusion as part of the upcoming STU 3 ballot.
  • We recognize that the timelines for making this occur are tight. In the event that a work group cannot make the changes requested, we invite them to, at minimum, provide an implementation note highlighting the intention to adjust each affected resource to align with the workflow pattern and to include a hyperlink to the "workflow.html" page. (This page doesn't exist yet, but it will.)
  • We also recognize that not all of these recommendations will fall into the 80% for all resources. Work groups are asked to do the following for each recommendation:
    • Apply the recommendation from the FHIR workflow task force as part of core
    • Create extensions to support those data elements that are relevant but not commonly used by the domain
    • Indicate that they feel the recommendation should not apply to their resource by posting an email to the fhirworkflow list server indicating why they believe a given recommendation is inappropriate for a given resource.
    • ((The list of resources believed to be impacted by the FHIR Workflow recommendations are provided in the attached spreadsheet. Most of the listed resources are categorized as either a "request" - a resource that indicates a specific intention for something to occur; or an "event" - a resource that represents a specific occurrence that could have been done in response to a request. A few event resources are marked with a question-mark as it's not clear whether they are requested or not. It's possible that one or more resources in the spreadsheet that were not categorized should in fact be listed as a "request" or an "event". Feel free to apply the workflow recommendations to uncategorized resources if you feel they should apply.
    • In addition to these categorizations, the workflow project calls for the Order and OrderResponse resources to be removed. They are superseded by Task. As well, the scope of ProcessRequest and ProcessResponse should be revised to leverage Task for the purpose of requesting the current state of a resource and for soliciting a state change.
  • The recommendations are as follows:
    • Request
      • Add a note in the introduction section that the resource is a "request" resource from a FHIR workflow perspective, including a hyperlink to workflow.html#request.
      • Rename the resource to [xxx]Request instead of [xxx]Order (request resources are used for plans, recommendations and proposals, not just orders
      • Ensure all of the data elements present in the "request" pattern document (attached) are present in the resource, keeping consistency with the naming where possible and adapting definitions to reflect domain-specifics
      • Ensure the status element for the resource has a terminology that aligns with the "request" states as well. (Note that all statuses related to fulfillment progress are now handled by Task.)
  • Event
    • Add a note in the introduction section that the resource is an "event" resource from a FHIR workflow perspective, including a hyperlink to workflow.html#event.
      • Ensure all of the data elements present in the "request" pattern document (attached) are present in the resource, keeping consistency with the naming where possible and adapting definitions to reflect domain-specifics
      • Ensure the status element for the resource has a terminology that aligns with the "request" states as well. (Note that all statuses related to fulfillment progress are now handled by Task.)
• From January 25 meeting: Lloyd shared the proposal to rename all request type resources to <resource>_Request. Seeking consistent name for all resources and term that encompasses larger swath of types of requests. An element beneath the tag instance would state the particular request, such as 'order'. This impacts the current Pharmacy Medication Order FHIR resource.

 Completed Action: Rx WG to discuss to determine if we agree or not. - agreed (with no vote) to comply with change but not needed to be made yet, per Lloyd

• Lloyd suggested that we hold off on making the change, if we decide to make the change. Wait for FHIR Infrastructure group to workout additional details before we make the changes. May have impact on how other data elements are name or included.
• Discussion: If we agree to the change, we'll need to review the description and other content for our resource to ensure that it accurately reflects the usage. This type of change will mean changes for implementers and it may not be as intuitive for implementers.
  • No decision to be made today. Will consider on a future call
  • Discussion - July 11 Meeting
    • John described the change proposed - we can alias resource to include MedicationOrder
    • Moved by John - seconded by Marla to add note to introduction section to Medication Order Add a note in the introduction section that the resource is a "request" resource from a FHIR workflow perspective, including a hyperlink to workflow.html#request. and to add an implementation note highlighting the intention to adjust each affected resource to align with the workflow pattern and to include a hyperlink to the "workflow.html" page. - 7/0/0 Carried
    • Moved by John - seconded by Marla to add note to introduction section to Medication Dispense, MedicationAdministration, MedicationStatement - Add a note in the introduction section that the resource is a "request" resource from a FHIR workflow perspective, including a hyperlink to workflow.html#request. and to add an implementation note highlighting the intention to adjust each affected resource to align with the workflow pattern and to include a hyperlink to the "workflow.html" page. 7/0/0 Carried

TR 12340 - Guidance for Substance abuse

• Michelle Miller introduced on 11/10/16 call.
• should MedicationStatement be used to document substance abuse
• although, substance abuse tracking forms usually have more than can be documented in MedStatement. e.g., desire to quit
• John:
  • classic clipboard at visit, are you taking these meds - each is a MedicationStatement
  • other "active products" - tobacco, alcohol, abusable substances - are handled as observations
• but, if the clipboard asked "do you use illegal substances" ... need support Y/N/no response. This seems to be a MedicationStatement (need to support negation and no answer)
• broader consideration: how to support MedicationStatement negation - is it MedicationStatment.notTaken ?
  • similar to assertions of Condition Absence (see Condition resource ... 9.2.3.5)
  • Note this is in a Zulip chat as "Substance Abuse"

Action: Michelle will create tracker item for this topic.  at least to come up with our position.  Create an example of how to use (or not use) pharmacy resources

Harmonization of Statement with Event

• 11/10/16 brief discussion on mapping MedicationStatement to Workflow Event

GF#12148

• requests common search parameters across resources. One of the requests is for date across medication resources - but the medication resources do not have any common date related search parameters. I would suggest that there should be a 'date' on each of them.
  • MedicationRequest datewritten rename to date
  • MedicationAdministration effective-time - add date with same definition
  • MedicationDispense - whenhandedover rename to date
  • MedicationStatement - add date = MedicationStatement.dateAsserted
  • Some ideas:
    • 1 - I would have thought that when comparing MedicationStatements with MedicationAdministrations and other medication resources, the date of interest was the the 'date of medication use', not the 'date of assertion'. So MedicationStatement's search date should be based on effective.
    • 2 - This would be an opportunity to align the names of MedicationAdministration.effectiveTime[x] and MedicationStatement.effective[x].
    • 3 - The information that can be held by the combined data elements effectiveDateTime and effectivePeriod can also be held by two different data elements date and duration. That design would give a common date data element for searching without adding an extra data element just for searching.

  • want to be able to query against building blocks separately - but dispense request doesn't have it's own identifier
  • Discussion of Use Cases
    • trying to only create new clinical data when something has changed
    • initial thought is that DispenseRequest should not be separated from MedicationRequest - believe can use existing resources
